PLOW.

SPECIFICATION forming part of Letters Patent No. 587,512, dated August3, 1897.

Application filed October 12, 1896. Serial No. 608,591. (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL G. SEVIER, a citizen of the United States,residing at Oenaville, in the county .of Bell and State of Texas, haveinvented certain new and useful Improvements in Plows, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming a part hereof.

My invention has relation to improvements in turning-plows; and itconsists in the novel arrangement and combination of parts more fullyset forth in the specification and pointed out in the claims.

In the drawings, Figure 1 is an elevation of one side of the plow. Fig.2 is a section on 00 w of Fig. 1. Fig. 3 is a detail top view of thedetachable and adjustable bracket by which the driving-wheel andrevolving moldboard are carried. Fig. 4 is an elevation of the oppositeside of the plow. Fig. 5 is a face elevation of the revolving moldboard.Fig. 6 is a detached View of the bracket shown in Fig. 3, but taken inface elevation. Fig. 7 is an elevation of one of the halves constitutingthe dirt-protectin g cup or casing for the gearing, and Fig. 8 is abottom plan View of the complete cup or the two halves assembled.

The general object of my invention is to construct a turning-plowwherein an adj ustment in a vertical plane between the plowshare, on theone hand, and the driving-wheel and rotating moldboard, on the otherhand, may be readily accomplished, the specific object thereof being toeffect such adjustment in a simple mechanical manner, thereby materiallycheapening the cost of construction of the plow. It is of courseunderstood that such adjustments are necessary, according to thecharacter and hardness of the soil passed over, different soilsrequiring to be plowed to different depths.

A further object is to effective] y protect the gearing from anypossible access of dirt from the surface over which the plow is passed.

In detail the invention may be described as follows:

Referring to the drawings, 1 represents a plow-frame made of one piece,to the rear end of which the handles 2 are secured, from which handlesextends forwardly the plow-beam 3. To the curved basal portion of theframe is secured the plowshare 4, of any approved design. Movablysecured to the standard of the plow-frame at a suitable point above thelower edge thereof and adapted to be adjusted in a vertical plane alongsaid frame is an independent detachable bracket or plate 5, the forwardexpanded portion of which is provided with suitable elongated slots 6,through which are adapted to be loosely passed the projecting headedportions of suitable bolts 7 carried by the frame, the heads of saidbolts being adapted to be countersunk into the body of the bracket, soas to come flush with the surface thereof.

The vertical elevation of the bracket along the frame can be adjusted byfirst loosening the terminal nuts 7 of said bolts, moving the bracket tothe desired position,and then firmly screwing the nuts against the bodyof the frame. The rearward extension or arm 5 of the bracket is adaptedto support one member of an angular or bent axle 8, the latter beinginserted into a suitable opening in the bracket and then secured by abolt 9, passed from the outer edge of the arm and into a cavity ordepression of the axle member, the head of the said securing-bolt beingcountersunk within the bracket.

Form ed integrally with the outer end of the rearward extension 5 of thebracket is a lug 10, to which is secured one end of a scrapingarm 11,the scraping end of the latter cleansing at all times the periphery ofthe drivingwheel 12, mounted on the axle member adjacent to the bracket5.

Forming a part of the driving-wheel 12 and embracing the axle member onwhich the wheel is mounted is a bevel gear-wheel or pinion 13, about thebase of which is formed an annular groove or depression 14, for apurpose to be subsequently referred to. The bevel-pinion 13 meshes witha similar hollow bevel-pinion 15, mounted loosely on the second memberof the bent axle, the said pinion 15 being provided with a tubularextension 15, to the basal flanged portion 16 of which the revolvingmoldboard 17 is secured. The outer projecting end of the member of thebent axle, by which the pinion 15 and moldboard 17, secured thereto,arecarried,is square or polygonal, (see Fig. 5,) said polygonal end beingadapted to fit a correspondingly poly onal opening of one end of ascraping-arm 18, the arm being secured firmly by a screw 10. Thescraping-arm 18 of course cleanses the surface of the moldboard againstwhich the earth thrown up by the plowshare impmges.

Projecting outwardly from the angle of the bent axle is an arm 20,through the outer end of which is passed transversely a pin 21, said pinbeing adapted to connect the projecting lugs 22 of the respective halvesof a cup or casing 23, adapted to envelop and fully protect the gearingbetween the pinions 13 and 15. Each half of the cup is provided with asemicircular cut-away portion or opening 24 along the edge thereof forsnugly embracing the tubular extension 15 of the pinion 15. The edge ofthe cup when properly mounted on the machine is adapted to enter and bereceived by the annular groove or depression 14 above referred to,whereby any dirt carried by the driving-wheel is deflected by the cupfrom the gearing with which it would otherwise come in contact.

It is apparent from the above that by reason of the adjustment of thebracket 5 along the frame 1 in a vertical plane the rearward extensionor arm 5, by which the bent axle S is supported, is likewise adjusted.Accordingly the vertical adjustment of the drive-wheel and revolvingmoldboard mounted in said extension is simultaneously accomplished, therelative positions of the drive-wheel and moldboard and their respectivescrapers remaining always the same.

It is further apparent that absolutely any and every particle of dirt orsoil is kept from the gear mechanism, thus eliminating the danger ofclogging the moving arts of the machine.

Having described my invention, what I claim is- 1. In a plow, a suitableframe, a plowshare carried by the same, an independent detachablebracket or plate carried by the standard of said frame and capable ofvertical adj ustment along the same, a bent axle secured to the bracketand adapted to support respectively the driving-wheel of the plow andthe revolving moldboard, and means forming a part of said axle forsupporting a suitable gear-protecting casing or cup, substantially asset forth.

2. In a plow, a suitable frame, a plowshare secured thereto, a bracketcarried by the frame and capable of adjustment along the same in avertical plane, a bent axle secured to the bracket, a driving-Wheelmounted on one of the members of. the axle, and having formed integrallytherewith a bevel-pinion directly embracing the member, an annulargroove formed at the base of the said pinion, a second pinion mounted onthe second memberof the bent axle and having a tubular extension forminga part thereof and embracin g the member on which said pinion ismounted, a flange formed at the extremity of said tubular extension, amoldboard secured to said flange, and a gear-protecting cup carried bythe bent axle, the edge of the cup being received by the annular grooveformed at the base of the pinion carried by the driving- Wheels,substantially as set forth.

3. In a plow, a suitable frame, a bracket carried by the same andadjustable thereon in a vertical plane, a bent axle carried by thebracket, a driving-wheel having apinion loosely mounted on one member ofthe bent axle, a revolving moldboard mounted on the second member of thebent axle, a bevel-pinion secured to the moldboard and meshing with thepinion carried by the driving-wheel, an arm projecting outwardly fromthe angle of the bent axle, a pin driven transversely through the outerend of the arm, a suitable gear-protecting cup composed of two parts orhalves, each half having formed integral therewith a lug by which therespective halves are adapted to be secured to the transverse pincarried by the arm projecting from the angle of the bent axle, and eachhalf having a substantially semicircular opening or cut-away portion forsnugly embracing the bevel-pinion of the moldboard, and an annulargroove or depression formed at the base of the pinion carried by thedriving-wheel for receiving the edge of the cup, whereby all dirtcarried up by the driving-wheel is deflected by the cup and the gearingbetween the cooperating pinions is protected, substantially as setforth.

4:. In aplow, a suitable frame, an independent detachable bracket havingan expanded portion, elongated openings or slots formed in the expandedportion, suitable bolts carried by the standard of the frame and adaptedto enter the slots of the bracket, whereby the latter can be bodily andvertically adjusted along the frame, a rear extension or arm forming apart of the bracket, said extension being adapted to support the axle ofthe driving-wheel and revolving moldboard of the plow, substantially asset forth.

5. In a plow, a suitable bent axle adapted to support respectively thedriving-wheel of the plow and a revolving moldboard, and means formingpart of said axle for supporting a suitable gear-protecting casing orcup, substantially as set forth,

In testimony whereof I affix my signature in presence of two witnesses.
